Vascular sonography is a challenging yet rewarding profession. As a vascular sonographer working in this field, you’ll use ultrasound equipment to produce images of patients’ veins and arteries using high-frequency sound waves. Physicians use the images—which show the structure and movement of internal organs, or blood moving through vessels—to diagnose and treat various conditions. In this role, you’ll also provide information and support to patients, while being an important part of the medical team.


To earn credentials in Vascular Sonography using the postprimary pathway, you must maintain compliance with the ARRT Standards of Ethics and fulfill additional requirements in structured education, clinical experience, and examination. You must also meet a supporting discipline prerequisite. For Vascular Sonography, you must first be certified and registered in Radiography, Nuclear Medicine Technology, Radiation Therapy or Sonography. Your Nuclear Medicine Technology credentials may be through ARRT or the Nuclear Medicine Technology Certification Board (NMTCB). Your Sonography credentials may be through ARRT or the American Registry for Diagnostic Medical Sonography (ARDMS).
